Reviewers agree the Sennheiser HD 550 is a comfortable, lightweight open-back headphone with a neutral, well-balanced sound and excellent mid-range clarity, making it a strong value, especially under $300.
9:32The reviewer finds the Sennheiser HD 550 to be an excellent, comfortable, and lightweight open-back headphone with a neutral sound signature and a bit of extra treble sparkle. They consider it a great value, especially when on sale, and believe it makes more expensive Sennheiser models like the HD 600 seem less necessary. The main caveats are a lean bass response and a treble spike around 10 kHz, but overall it's an easy recommendation.
32:08The reviewer and his colleagues find the Sennheiser HD 550 to be a surprisingly strong performer, essentially a refined and improved version of the HD 560s with a neutral, well-balanced sound. While they note some minor drawbacks like a slightly dry presentation and less premium build compared to the HD 6 series, they overall consider it a very good headphone that is comfortable and offers excellent mid-range clarity.
19:44The reviewer praises the Sennheiser HD 550 as an excellent open-back headphone that blends the 500 series comfort with 600 series sound quality. It offers a near-perfect mid-range, good bass extension, and reduced clamp force for long listening sessions, making it one of the best values under $300. The main criticism is that it was released too soon after the similar HD 505, but the 550 is considered the superior tuning.
9:15The reviewer finds the Sennheiser HD 550 to be an excellent, natural-sounding headphone that excels in mid-range and vocal intimacy, though it falls slightly behind competitors in detail retrieval and soundstage width. It is considered the best of the 5-series, with a low amplification barrier and comfortable design, making it a strong recommendation for sound quality over comfort-focused alternatives.
15:49The reviewer compares the Sennheiser HD 600 and HD 550, finding both to be excellent value but with distinct characters. The HD 550 is more neutral and better extended in the bass, while the HD 600 offers a richer, more lush sound with a bit more treble sparkle. The reviewer concludes that the HD 600 is more fun and forgiving for rock, while the HD 550 shines with jazz and clarity, making the choice genre-dependent.
27:20The reviewer compares the Sennheiser HD 550 with the HD 505 and HD 560S, finding them 95% similar in design and sound. The HD 550 is the most expensive at $350, with a slightly refined sound and lighter clamp, but the differences are minor. The reviewer concludes the HD 550 is a solid but incremental upgrade, and suggests the HD 505 or HD 560S may offer better value depending on preferences.
